Appeal No. 1997-0653
Application No. 08/140,043
BACKGROUND
Appellants’ invention relates to an adaptive video file server and methods for its
use. The system retrieves audio/video data compressed in a first standard from storage
and compresses the retrieved audio/video data using a different standard than the first
standard. The system then transmits the data compressed according to the second
standard to subscribers via at least one of various available formats. An understanding of
the invention can be derived from a reading of exemplary claim 63, which is reproduced
below.
63. A video file server for storing video data and transmitting
compressed video data to a plurality of subscriber systems, said video file
server comprising:
a main unit controller for controlling transmission of compressed
video data to subscriber systems;
a random access data storage subsystem for storing compressed
video data and from which such data is randomly retrievable;
a plurality of communication subsystems, for transmitting compressed
video data to the subscriber systems; and
compressed video data format conversion subsystem for receiving
compressed video data from said random access data storage subsystem
that is compressed in accordance with a first compression standard, for
converting the received compressed video data from the first compression
standard to a second compression standard that differs from the first
compression standard, and for transmitting such converted compressed
video data compressed in accordance with the second compression
standard to at least one of said communication subsystems.
